MLB 13 The Show PS3 help?

I recently got MLB 13 The Show and it freezes after the opening video. I've moved it from external to internal and ran it on BD Mirror but that didn't help at all. I'm running it on Rogero 4.46 and I've bee able to play other games that are new and old so I'm at a lose as of what to do. If anyone has any suggestions that would be greaatttt.
